1.2 Main Components
Processor Subsystem
The processor subsystem is built around the AMCC 440GX integrated processor, the QLOGIC
ISP2312 dual Fibre Channel I/O Controller and the PCI6540 PCI-X to PCI-X bridge. The Processor
Subsystem is located on the Primary PCI segment (PCI-X).
The processor subsystem block diagram is shown in figure Figure 1-2:

AMCC 440GX Embedded Processor
The AMCC 440GX provides a powerful PowerPC CPU core, a 256MiB local DDR-SDRAM
memory, a 32MiB FLASH memory, two 10/100/1000Mbps Ethernet connections, two 10/100Mbps
Ethernet connections and two serial connections (RS-232 or RS-422) .
Additionally the AMCC 440GX processor provides simple connectivity of additional peripheral
devices through an external local bus. This is used for register access to the board PLD.
For debug purposes, JTAG and CPU control signals are provided to a connector for use with
WindRivers VisionProbe tools. This allows CPU bring-up and boot before the FLASH is initialized
and low-level software debug using the same tool.
